WATER-HEATER.

Specification of Letters Patent.

Application filed. January 20, 1920. Serial No. 352,805.

T 0 all whom it may concern.

Be it known that I, SAMUEL C. SMITH, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Water-Heaters, of whichthe following is a description.

My invention belongs to that general class of devices known as heatersand relates particularly to a heater attachment to be used in connectionwith gas, oil,v or other stoves, for heating water. The device isparticularly adapted to be employed upon any of the well known types ofgas, oil, or other stoves now on the market, Without materially changingor rebuilding the stove. The invention has among its objects theproduction of a device of the kind described that is simple, convenient,durable, efiicient, economica-l, and satisfactory for use wherever foundapplicable. It has particularly as an object the production of'thedevice of the kind described that will almost instantly heat the waterto a high temperature, and which may utilize the heat or flame which isat the same time used for heating or cooking purposes. There more thanone heater is employed upon the stove, the same also may be utilized asa warmer, taking the place of a warming oven. Many other objects andadvantages of the construction herewith shown and described will beobvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangementand combination of parts herein shown and described, and moreparticularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like orcorresponding parts,

Figure 1 is a plan view of a portion of a gas stove equipped with aplurality of heaters;

Fig. 2 is a sectional view taken substantially on line 2-2 of Fig. 1;

Fig. 3 is an enlarged sectional view taken substantially on line 3-3 ofFig. 2;

Fig. 4 is a sectional view taken substantially on line 44 of Fig. 8;

Fig. 5 is a plan view of a slightly modified construction;

Fig. 6 is a sectional view taken substantially on line 6-6 of Fig. 5;

Fig. 7 is a sectional view taken substantially on line 7-7 of Fig. 5;and

Fig. 8 is a sectional View taken substantially on line 8-8 of Fig. 7.

Referring to the drawings, 1 represents one or more gas burners of anydesired type, that shown being a type in which there is provided aplurality of small holes or openings through which the gas escapes andmay be lighted; The particular burner shown is also of the star shapedesign. I'have shown a portion of the gas stove, consisting of the toppart 2 with the parts 33 carried there by and which carry the arms 4,upon which the articles to be heated in vessels or pots are supportedabove the flames.

Any number of heaters or heater units one will suffice for all. The typeof heater shown in Figs. 1 to 4: inclusive, consists of a plate 6,having a flange 7 about the out side of the same, 8 being a platearranged upon the opposite side, and 9 a gasket or the equivalent,preferably of copper or the equivalent. The parts 6 and 8 may be securedtogether by bolts or screws 10, or the equivalent, for the purpose. Thepart 6 is provided with a plurality of extending or projecting parts 11,which closely fit against the gasket, 9. These parts are formed withopenings 12 through the same so that they are tubular, and theysubstantially const1tute a series of fines. The gasket 9 and plate 8 areformed with openings or apertures 15 and 16 respectively therethrough.The flues in the preferred construction are arranged so that theyregister with the openings 17 in the burner, and the heater is set downsubstantially close to the burner or is supported thereon if desired.Their arrangement, shape and size generally corresponds to the shape ofthe burner, and the size, shape and location of the openings in theburners. The heater is provided with shown, and the gas turned on andlighted, the flame will extend from or through the openings 12 and heatthe articles carried on the arms 4. Obviously a part of the heat will bedistributed in the plate 6 and through the fines 12. I have found frompractical experience that the heater is sub- .stantially instantaneousin operation and that the same does not interfere with the usual use ofthe stove.

In the construction shown in Figs. 5 to 8, the operation is the same,but in this case there is shown substantially two elongated fines. Thisparticular type is mounted above the burner similar to the otherconstruction described. Referring to the figures, 28 and 29 representtwo spaced tubular shells having chambers 31 formed thereon. The twoparts however, are spaced so that there are spaces substantiallyconstituting lines between the inner and outer parts. They are connectedhowever, as at 3232, and provided with an inlet pipe 33 and a dischargepipe 8 Obviously as the heat passes up betweenthe two shells it heatsthe contents of the same.

Having thus described my invention it is obvious that various immaterialmodifications may be made in the same without departing from the spiritof my invention; hence I do not wish to be understood as limiting myselfto the exact form, construction, arrangement and combination of partsherein shown and described or uses mentioned.

VJhat I claim as new and desire to secure by Letters Patent is:

1. A water heater of the character described, comprising a chamberformed of cooperating parts, a water feed inlet at one portion of thechamber, and a water di charge conduit at another portion thereof, saidchamber having a plurality of noncommunicating flues disposed in anirregular path so as to present a maximum heating surface to the waterentering the chamber to intensely heat the same prior to its discharge,and a burner disposed beneath noncommunicating flues to permit heatinggases to pass through the lines.

2. A water heating attachment, comprising a chamber consisting of twoparts, a water inlet to said chamber and a water discharge leadingtherefrom, one of said parts having extensions projecting therefrom, aplurality of separated vertically disposed fiues passing through saidextensions through apertures in alinement with the fines in the otherpart forming said chamber, the flues receiving heating gases tointensely heat water surrounding the projecting parts prior to thedischarge thereof.

8. A ,water attachment of the kind described, comprising a water chamberhaving an inlet and outlet, the walls of said chamher being providedwith extensions disposed in an irregular path and surrounded on bothsides by the water introduced to the chamher, said extensions beingformed with a plurality of vertical bores passing therethrough separatedfrom one another by the material of which the extensions are formed andconstituting a series of flues.

4. A heater of the character described, comprising separated membersforming a chamber, a water inlet leading to said chamher and an exhaustleading therefrom, one of said members having a plurality of projectingextensions disposed in an irregular path and adapted to be surrounded bywater introduced to the chamber, said extensions having separated finespassing therethrough, the other member of said chamber being providedwith. apertures alining with said flue openings.

In testimony whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
